I had one of these when i lost my licence for 6 months a year and a half ago. i modded the zorst so it had twin outlets, it gave it heaps more pull and would sit on 60 on the flat. Best of all i hardly had to peddle up hills. lol

I built one when i was younger from a heavy duty 160cc whipper snipper engine had it mounted above the rear tyre and used a skateboard wheel to drive it i welded up the centrifugal clutch so it was direct drive and it was capable of doing 85 k's .
I will never forget the looks i used to get from car drivers when they were doing 60 and i went past them .
I did experiment with a lawnmower engine midmounted in a bmx bike but i swapped the sprockets around and the gear ratio was 2 high going down a steep hill flat out it just started firing then the chain come off and i had no brakes was enough to scare me off the thing.
